What is the oxidation state of C in CO2?

Mr. Mullins has died in Dallas, Texas. His family wishes to have the ceremonies and interment in Obion County, KY. Your funeral home is going to charge the fee for this transfer. What is this fee called on your General Price List?

Calculate the Ecell for the following reaction 2Al(s)  +  3 I2(s)  →  2Al3+(aq)  +  6 I-(aq)  Two half-cell potentials Al3+(aq)  +  3e-  →  Al(s)    Ecell = -1.66 V I2(s)  +  2e-  →  2I-(aq)  Ecell = +0.54 V Hint: Half-cell with the most positive potential gets reduced. 

Consider the following equation: Fe2O3(aq)  +  3CO(g)    →   2Fe(s)  +  3CO2(g) Identify the species (element or ion) that is acting as the oxidizing agent

What statement is true for the following half cell reaction F2(g)  +   2e-  ↔  2F-(aq)  Ecell = + 2.87 V

Deathcare that minimizes the use of energy in service, and offers products that ban the use of toxic or hazardous materials is called

The burning chamber in a crematory is called a

What is the proper term used to describe the initial notification informing a funeral home that a death has occurred?

Consider the following half-cell reactions: Zn2+(aq)  +  2e-  ↔  Zn(s)  Ecell = -0.76 V Cu2+(aq)  +  2e-  ↔  Cu(s)  Ecell = +0.34 V Identify the species (element or ion) that is acting as the reducing agent Hint: The half-cell with the highest positive potential gets reduced

Two half-cell reactions are shown below: Fe2+(aq)  +  2e-   ↔  Fe(s)     Ecell = – 0.44 V Cu2+(aq)  +  2e-  ↔  Cu(s)    Ecell = +0.34 V Hint: The half-cell with the highest positive potential gets reduced. the other half-cell must get oxidized. Find the Gibbs free energy for the above cell reaction (ΔG = -nFE: F = 96485 C, n = no. of electrons and E = cell potential). Use the cell voltage you received in questions 21.
